Ferdinand arrived on a free transfer from Manchester United, whilst Sandro completed a deadline day switch to Loftus Road for a fee believed to be £10 million.
Whilst players of their talents and experience may have been expected to get the Hoops off to a flying start, Harry Redknapp’s side sit bottom of the Premier League table after seven games played, with just one victory and one draw leaving the West Londoners with four points.
Ferdinand has started every game for the side who have conceded 15 goals - more than one a game - and has looked slow and well below the highs expected from the 35-year-old. Despite his age, he still performed admirably when called upon for the Red Devils last season, and his loss of form since moving south should see him removed from the first-team if the situation does not improve.
Sandro arrived at Loftus Road after a four-year spell with Spurs, having been brought to the club by current R’s boss Redknapp, making over 100 appearances in all competitions for the Lilywhites. He has adapted even worse than Ferdinand, making just three appearances in the midfield and giving away more than a foul a game.
Not only have the duo come under criticism from fans, the Evening Standard ran a poll to discover who had had the worst impact with the Loftus Road outfit since their arrival - with the pair coming out top.
Ferdinand and Sandro were given a D rating, alongside Eduardo Vargas and Mauricio Isla, for their impact this season. The highest rated signings were Niko Kranjcar and Leroy Fer, with the pair of midfielders given B ratings after a series of impressive displays.
Many had high hopes for Rangers with the arrival of Ferdinand and Sandro over the summer, but they will surely need to step up their game if they intend to prevent QPR’s slide back to the Championship - something that is looking increasingly likely with every passing week.
